Internal carotid artery
Which artery is labeled by #6?
Posterior ethmoidal artery
Which sinuses drain into the inferior meatus?
None - Nasolacrimal duct only
Which nerve is labeled by #15?

Which nerve pierces the thyrohyoid membrane?
This would be between which two constrictor muscles of the neck?
What does it innervate?
Internal (recurrent) laryngeal nerve
- Between the middle and inferior constrictor
- Motor to the intrinsic laryngeal muscles (except cricothyroid)
- Visceral sensory to the larynx below the vocal cords
Which space is labeled by #2?
Which nerves does it carry?

Which nerves are labeled by #10?
Orbital branches of the maxillary nerve CN V2
Which vessel is labeled by #6?
Common carotid artery
Which muscle is labeled by #1?
What are its attachments?
Superior pharyngeal constrictor
Pharyngeal tubercle (of the basilar part of the occipital), continues as the buccinator anteriorly
(Technically attaches to the pterygomandibular raphe, and then continues as the buccinator but this wasn’t really empasized)

This is between which two constrictors of the neck?
What does it innerate?
Glossopharyngeal nerve (CN IX)
- Betwen the superior and middle constrictor
- Visceral sensory to the pharynx
- Initiates the gag reflex
Which sinuses drain to the superior meatus?
- Posterior ethmoid
-
Sphenoid
- To the spheno-ethmoidal recess, within the superior meatus?
Which fascia is labeled by #2?
Pretracheal fascia
Which structure is labeled by #12?
(Which structures are separated by this opening?)
Faucial isthmus
Opening between the oral cavity and the oral pharynx
Which nerve is labeled by #16?
What nerve fibers does it carry?
Greater palatine nerve
- Sensory fibers from the maxillary nerve CN V2
- Parasympathetic and sympathetic fibers from the nerve of the pterygopalatine canal
- Parasympathetic from the greater petrosal nerve (From CN VII)
- Sympathetic from the deep petrosal nerve
